Information presentation device, and information presentation method

Abstract

There is provided an information presentation device that is configured to present information, to a plurality of users that differ in level, in such a manner that each of the users can easily understand the information, and an information presentation method. The information presentation device includes: an identification unit that identifies respective levels of one or more users; an obtaining unit that obtains presentation information to be presented to the users; a conversion unit that appropriately converts the obtained presentation information according to the level of each user; and a presentation unit that presents the appropriately converted presentation information to each user. The present technology can be applied to, for example, a robot, a signage device, a car navigation device, and the like.

The invention claimed is: 
     
       1. An information presentation device comprising:
 an identification unit configured to identify respective levels of one or more users; 
 a detection unit configured to detect a respective state of each respective user of the one or more users by detecting whether or not the respective user is watching a display; 
 an obtaining unit configured to obtain presentation information to be presented to the one or more users; 
 a conversion unit configured to appropriately convert the obtained presentation information according to the level of each user; and 
 a presentation unit configured to present the appropriately converted presentation information to each user, 
 wherein the identified respective levels of the one or more users are estimated based on collected conversations of the one or more users, 
 wherein, in a case where a first user of the one or more users who is watching the display and a second user of the one or more users who is not watching the display concurrently share the information presentation device, the presentation unit presents the appropriately converted presentation information by displaying characters of the appropriately converted presentation information for the first user who is watching the display, and outputting a synthesized voice of the appropriately converted presentation information to the second user who is not watching the display, and wherein the identification unit, the detection unit, the obtaining unit, the conversion unit, and the presentation unit are each implemented via at least one processor. 
 
     
     
       2. The information presentation device according to  claim 1 ,
 wherein the identification unit identifies, as the respective level of each respective user, at least one of an age, a knowledge level, language ability, or a foreign-language learning level of the respective user. 
 
     
     
       3. The information presentation device according to  claim 2 ,
 wherein the identification unit identifies the respective level of each respective user on the basis of information that is registered in a database beforehand. 
 
     
     
       4. The information presentation device according to  claim 3 , further comprising:
 an estimation unit configured to
 estimate the level of each user, and 
 register the estimated level in the database, 
 
 wherein the estimation unit is implemented via at least one processor. 
 
     
     
       5. The information presentation device according to  claim 4 ,
 wherein the estimation unit is further configured to
 periodically execute processing of estimating the level of each user, and 
 update the registered level of each user in the database. 
 
 
     
     
       6. The information presentation device according to  claim 2 ,
 wherein the presentation unit presents the appropriately converted presentation information to each user by at least one of character display or voice output. 
 
     
     
       7. The information presentation device according to  claim 2 ,
 wherein in a case where a plurality of users that differ in level concurrently share the information presentation device, the presentation unit presents the appropriately converted presentation information by displaying characters of the appropriately converted presentation information for a lower level user, and outputting a voice of the appropriately converted presentation information to a higher level user. 
 
     
     
       8. The information presentation device according to  claim 2 , wherein
 the conversion unit converts the obtained presentation information by converting words contained in the obtained presentation information into plainer words according to the level of each user. 
 
     
     
       9. The information presentation device according to  claim 2 , wherein
 the conversion unit converts the obtained presentation information by converting Chinese characters contained in the obtained presentation information into at least one of hiragana characters, katakana characters, or Chinese characters with reading of the Chinese characters according to the level of each user. 
 
     
     
       10. The information presentation device according to  claim 2 , wherein
 the conversion unit converts the obtained presentation information by converting a part or all of the obtained presentation information into a foreign language according to the level of each user. 
 
     
     
       11. An information presentation method of an information presentation device, the method being executed by the information presentation device, the method comprising:
 identifying respective levels of one or more users; 
 detecting a respective state of each respective user of the one or more users by detecting whether or not the respective user is watching a display; 
 obtaining presentation information to be presented to the one or more users; 
 appropriately converting the obtained presentation information according to the level of each user; and 
 presenting the appropriately converted presentation information to each user, 
 wherein the identified respective levels of the one or more users are estimated based on collected conversations of the one or more users, and 
 wherein, in a case where a first user of the one or more users who is watching the display and a second user of the one or more users who is not watching the display concurrently share the information presentation device, the appropriately converted presentation information is presented by displaying characters of the appropriately converted presentation information for the first user who is watching the display, and outputting a synthesized voice of the appropriately converted presentation information to the second user who is not watching the display. 
 
     
     
       12. A non-transitory computer-readable storage medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
 identifying respective levels of one or more users; 
 detecting a respective state of each respective user of the one or more users by detecting whether or not the respective user is watching a display; 
 obtaining presentation information to be presented to the one or more users; 
 appropriately converting the obtained presentation information according to the level of each user; and 
 presenting the appropriately converted presentation information to each user, 
 wherein the identified respective levels of the one or more users are estimated based on collected conversations of the one or more users, and 
 wherein, in a case where a first user of the one or more users who is watching the display and a second user of the one or more users who is not watching the display concurrently share the information presentation device, the appropriately converted presentation information is presented by displaying characters of the appropriately converted presentation information for the first user who is watching the display, and outputting a synthesized voice of the appropriately converted presentation information to the second user who is not watching the display.
